WINDOW-SCREEN.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed August 2'7, 1913. Serial No. 786,874.

To all whom. it may concern:

Be it known that I, FRANK M. GUSTIN, citizen of the United States, residing at Durand, in the county of Shiawassee and State of Michi an, have invented certain new and useful mprovements in \Vindow- Screens, of which the following is a specification.

The present invention relates to new and useful improvements in window screens, and has particular reference to that type of such devices which are adjustable.

As its principal object, the present inven tion contemplates the provision of a window screen so constructed that it may be expanded or contracted either vertically or horizontally, to adapt it for application to windows of any height and width, within a reasonable range.

An object of equal importance with the foregoing is to construct a screen of this character with such regard to number, proportion and arrangement of parts that it may be cheaply manufactured, will be durable and efficient in its action, and may be applied to any window casing of the usual type.

The above, and additional objects are accompli'shedby such means as are illustrated in the accompanying drawings, described in thefollowing specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

l-Vith reference to thedrawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a front elevation illustrating the screen in assembled position in a window casing and illustrated with the two major sections in horizontal alinement. Fig.2isafront elevation illustrating the frame in assembled position within a window casing, with the major sections in vertical alinement. Fig. 3 is a perspective view of the screen in disassembled relation with the two major sections in horizontal alinement illustrating the major sections in extended position and further disclosing the minor sections composing the two major sections in slightly extended position. Fig. 4 is a section on the line 44 of Fig. 1. Fig. 5 is a detail fragmentary section of acorner of the female major section illustrating particularly the manner in which the male and female minor sections of which the female major section is composed are slidably inter-fitted. Fig. 6 is a detail fragmentary section of the male major section, disclosing particularly the manner in which the male and female minor sections of which the male major section is composed inter-fit. Fig. 7 is an enlarged perspective view illustrating the two minor sections of the female major section extended approximatelyto the limit of their adjustment. Fig. 8 is an enlarged fragmentary perspective of the male major section. Fig. 9 is a detail fragmentary view illustrating the male and female sections of the female major screen section in disassembled relation disclosing particularly the manner in which the interfitting flanges of the two sections are slidably connected.

Proceeding now to the description of the drawings the numerals 10 and 11 designate respectively, and as entireties, the two major sections of which the screen is formed. Each major section consists of a pair of separate elements, substantially rectangular in shape, which are adjustably and slidably connected.

In the preferred embodiment the two ma jor sections are in turn slidably and adj ust-' ably connected, it being therefore, apparent that when the major sections are arranged one above the other as in Fig. 1, they may be adjusted with such relation to each other that they will completely close-the window space. It will also be obvious upon reference to Fig. Q'that when mounted in hori- .zontal alineme'nt with each other the major sections may be expanded as when in ver tical positions to a! permit their application to a window of any width. Similarly it will be observed that when the screens are superposed one upon the other in vertical designate and 14. The minor section 13 of this female major section includes, as best illustrated in drawings, but is substantially similar to the interfitti'n minor sections, respectively, as entireties by the numerals 13 Fig. 7, a substantially rectangular frame,

, which is preferably made of sheet steel, al-

.though galvanized tin, or any other similar suitable material may be employed, and consists of top and bottom frame members 15 and 16 and a pair of connecting side-frame members17 and 18.. Wire screening, indicated at 1 9 is'secured to the rectangular frame above described, by means of spaced tongues 20'carried on the'members 16,17

and 18 and a turned edge carried on the upper frame member 15. The turned edge and the stamped tongues are both bent after the screening is in assembled position to clamp the edges of the screen firmly against the rear face'of. the frame members 15, 16, '17 and 18.. The turned edge'of the upper frame member 15' is not discernible in the turned edge 21 formed" on the lower framemember of the male section 14, as illustrated in Fig. 7, and its construction will there-- fore e apparentf'u on reference to this figure.- This-turns 'ed'ge on the upper frame-member 15 and the spaced tongues 20 g the\ tongues and the turned edge out of binding engagement with the a 'jacent faceare preferablymade" of relatively thin material, accomplished by-flattenmg or rolling them during the manufacturing of the screen,,the purpose in mind being to permit the user of the screen to apply new screening whenever desirable by merely pullingof'the frame-members 15,-16,-'1 and.1 8, as will be .readily--understood upon reference to the 'drawings'..;-,

In orderjto accommodate the flanges -car-' ried b' the male'fsection 14,-tobe hereinafter female major screen .secti n' descri so that the itwo sections of theaybe slidconnected, the side frame-members: 17

directed ata' slight an le to the body' portion of.the flanges so t at the flanges of the male minor section, one of which isYdesignatedat 23 in Fig. 9'may be easily inserted to lie between the portions .24 and 25 of the flanges 22 and 23. These members 22 and 23 are preferably of such width that their the body portion of the base outer edges terminate ati a point approximately one-third the'distance acrossthe face of the base-flange 27, carried by. the lower frame member 16 and extending at right angles therefrom, as clearly illustrated in Fig.7. Theouter ed e ofthls base flange 27 is directed upward y alt-right angles to ange and in parallel. spaced relation to the member 16.-

ab? I an 18"are.'providedfwith anned down" 'A' cross-sectionally L-shaped strip 28 is mounted longitudlnallyof the base-flange. 27 and is arranged with its vertical portion 30 in parallel spaced relation to the outer vertical or upturned edge 29 of the base flange, having its horizontal portion 31 disposed on the base flange 27 and securelyfixed thereon; )The free edge of the portion 31 carries an upwardly and inwardly. directed ,lip 32 which is adapted to receive a. straight edged flange or connecting strip carried by the male major section of the screen, as will be hereinafter fully described.

The male minor. section of the female major section heretofore designated as an entirety, by the numeral 14, is similar to t .the member 13' with one exception, that the.

cross-sectional U-shaped receiving flanges 22 and 23 of the section 13 are replaced by a,.pair of straight edged flanges 33 and 34, which are adapted for insertion in the flanges 22 and 23, as will be readily appar- 1 4 cut upon reference to Fig. 7, in which this feature of the invention is best illustrated.

As stated, this section 14 is similar in every other respect to the member 13 and "for purposesof clearness in-descriptionthe asefiange, L-shaped strip, and the associated parts of the section 14 will be hereinafter desi ated'by the same numerals, heretofore ascribed, to the corresponding parts of the section 13.

-Relative to the manner in whic'hthe sec:

tions 13 and- 14 of the major female sections are slidably connected, it will be noted upon reference to .Fig. 7, that the straight edge flanges33 and 34 of the member 14 are slidably mounted in the members 22 and 23 in section 13, so that the two sections may be. quickly and easily extended .or contracted,

to meet the requirements of the conditions incident to the application of the screen.

' Coming now to the description of the male maior section; which asilieretofo'r'e set forth, inc udes in the preferred embodiment, a pair of minor sections formed .in the. nature of interfitting 'male andfemalesections, the

numerals35" 36,Ydesignate respectively, 7

, secured t0;the rear face of the frame 'memher, be ng provided with a plurality of spaced tongues similar to the members? 20, hetetofore described. .A turned ed a; is formed on the rear face-of the upper ame in detail. I

the section36 carries an outwardly directed 'members 39 and the female section 36 are panned down to produce receivingflanges similar to the members 22 and 23 of the sec tion 13, heretofore described,.as indicated at 42 in Fig. 4. These receiving flanges 42 receive the straight edge flanges 43 formed on the side-frame members of the section 35, as will be'hereinafter more fully described The lower frame member 37 of straight edge flange 44 which is ofsuch size as to be insertible in the L-shaped strip 28, and is adapted to beheld against movement from the base thereof by the inwardly directed lip 32 as will be readily observed upon reference to Figs. 7 .and 8. It has been found necessary to form a notch 45 in the lower end of the receiving flange 42 so that the inwardly directed lip 32 may beaccommodated. I I

Passing now to the description of the male minor section 35 which is adapted to be slidably interfitted into the female section 36, it will be obvious upon reference to Fig. 8 that this member is' substantially similar to the member 36 with the exception 1 that the screening indicated at 46 is arranged on the inner face of the frame and the U-shaped receiving flanges 42 of the section 36 are replaced by the straight edge flanges 43. These flanges 43 are insertible in the receiving flanges 42 and permit the two minor sections 35 and 36, which coinprise the male major section to be adjusted -to increase or diminish their longitudinal dimension.

From the foregoing it will be observed, particularly'upo'n reference to Figs. 7 and 8, that the male major section may be slidably connected to the female major section and slidably adjusted therein by inserting the flanges 44 of the sections 35 and 36 in the strips 28 of the sections 13 and 14, so that when the two major sections are applied to a window in horizontal alinement,

.they may be extended or contracted to corpair of spring-actuated latch devices which are designated as entireties by the. numerals 47 and 48 and are respectively secured to the lower and upper frame members of the sections 36 and 35; As best illustrated in Fig.8 each 'of these spring-actuated latching devices includes a pivoted pawl 49 which is retained within a rectangular metallic housing 50 by a pivot pin 51 and is normally held with its forward terminal 52 exteriorly of the housing by means of a latch-spring 53. The forward terminals 52 of this pawl is formed with a notch indicated at 54. This notch is adapted to receive inwardly extending studs 01', pins carried by the upturned edge portions 29- of the female section, one of these studs being indicated at 55 in Fig. 4. A plurality of these stud pins are provided as indicated in Fig. 7, and it will be apparent that the engagement of these pins in the notches 54 of the pivoted pawls 49 will operate to hold the male major section of the screen against farther inward movement into the female section. The pawl may be pressed inwardly against the tension of the spring 53 and disconnected from the studs 55 by manipulation of the finger pin 56 which extends laterally from the pawl and is received within a cutaway portion 57 when swung inwardly toward the frame members 37.

In reduction to practice, I have found that the form of my invention illustrated in the drawings and referred to in the above description as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claims.
